ELECTRIC Application filed September and polishing. Another objectof'the in vention is to providea portable, electric moin tor operated, polishing implement, with a pair of handles, whereb it ma be easil manipulated, one of the andles eing pre erably removable and the other being angularly adjustable with respect to the 101151- I tudinal axis of the motor, whereby the evice may be reduced to a compact form for shipment or storage in a carton or other container. Another object is to provide an elec tric motor with one, or a pair of handles,

2 and with a relatively soft, pliable, polishing member, such as sheep skin, for attachment to an extension of the motor shaft such as a spindle. Another object is to provide a sheep skin polishing member, which may be folded along approximately straight lines about a pliable pad so as to present approximately straight edges, and having fastening means for readily attaching and detaching the polishing member to and from the pad. Other objects and advantages will appear in the course of this specification, and w1th said objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and claimed. 7

The invention is clearly illustrated in the drawing accompanying this specification, in which:

Fig. 1 is a side elevation, with certain parts broken out, of an electric polisher embodying a simple form of the present inven-.

tion; Fig. 2 is a plan thereof, with a. certain part broken out and Fig. 3 is a view partly in plan and partly in horizontal section thereof, the line of section being taken at 3-3 in Fig. 1.

Referring to said drawin which illustrates a simple embodiment of the present invention, the reference character 1 designates a portable electric motor of convenient size 59 and weight for handling, and of relatively low horse power. Secured to and projecting from the side of the casing of the motor are handles 3, 6, which project radially from the motor and are angularly disposed with respect to each other, being placed at a suitable angle whereby both of them may be POLISH.

taken hold of conveniently for the purpose of manipulatin the device. ence, the hand es are secured to a band 2, which surroundsand is secured'to the casing of the motor in any suitable manner, and as a preference one of the handles 3 is removably secured to said casing, it being here shown as provided with a threaded socket member 5 threadedly secured upon a thread- As of prefered stud, or screw, 4, which is secured to and projects from the band 2. The handlefi may be wholly disconnected from the motor whenever desired or necessary. The handle 6 is also secured to the band 2 and if desired may be pivoted thereto on an axis extending at right angles to the longitudinal axis of the motor whereby the handleG may be ad-v justed angularly with respect to the said axis for t 1e purpose of obtaining compact= ness and also for the purpose of enabling the user to hold the device more conveniently in reaching certain otherwise inaccessible portions of an article which is to be polished. The handle 6 contains an electric switch 8, which is interposed in the electric conductors 7 that extend through the handle and run to the motor 1. If desired the switch 8 may be covered by a two piece 'bakelite covering 9, which may be secured upon the handle 6 and around'the switch. Theelectric cords or conductors 7 should be of conven ient length and provided with a. plug (not shown) whereby electric" connection may be made withan electric socket of the usual house'wiring. In the form of the invention illustrated, a forked bracket 10 is provided, which is secured to the band 2 in any suitable manner, and the portion 6"of the handle is placed between the forks of the bracket and pivotally secured thereto by a rivet,

screw or other pivotal connecting member 11. A clamp bolt 12 extends through arcuate slots 10 in the forks'of the bracket 10 and through the part 6 of the handle and has a thumb or wing nut 13 threadedly secured upon the threaded end of the bolt 12 and furnishes means for securing the handle 6 upon the motor in any angular position of adjustment with respect thereto.

Upon the motor shaft 15 of the motor is secured a spindle 17, which carries upon its free end the polishing member 21. One end of-said spindle 17 is formed with a tapered, threaded, split end 18, which is arranged to receive a lock nut 16, and said tapered end of the spindle is formed with a socket for 55 may be swung down into. alignment with the ishing member 21 is removably secure have a screw threaded connection with the spindle, and secured to said disc 19 is a felt or other pliable, circular pad 20. The Otlo saidpad 20. In its present form saidpolishing member'is formed from a piece of sheep skin'or other relatively soft pliable material'and may be square in form,al-

thou h not necessarily so. The disc 19 and f LettersfPatent-z polis ing member 21 are provided with coacting fastening members 22- such as the ordinary snap fasteners whereby the polishing member may be detachably secured to said disc. Inattaching the sheep skin pol-j ishing member to, the pad, the pad is placed upon the middle of the sheep skin piece and the corners of said sheep skin piece are then folded over the pad along approximately straight lines thereby forming flaps 21?, which are fastened down upon the disc with the fastening members 22. It will therefore be seen that the polishing member, when secured on thepad, takes the shape of a square or other non-circular form, containing soft flexible corners that project considerably from'the' cylindrical face of the pad and form relatively soft pliable polishing elements, by which otherwise inaccessible parts of surfaces may be reached in. polishing them. I

In operation, the user grasps the handles 3, 6, closes the switch 8 thereby starting the motor 1, and lightly presses the flat face of rotating polishin member 21 against the surfaceof theo ject to be polished and moves the polishing member along the surface. thereof. At otherwise inaccessible places, the edge ofthe polishing member may be placed against the surface to be polished and inthis way corners and depressions can be reached, which would otherwise be inaccessible with around polishing member. For shipment or storage in cartons or other containers the handle 3 may be detached from the motor, and the handle 6 axis thereof, thereby reducing the greatest tion with polishing materials, liquid or.

paste. In case the polishing member becomes soiled or worn it may be readily detached from the pad and cleaned or replaced.

More or less variation of the exact details of. construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend, in the following claims, to point out all of the invention disclosed herein. 1

I claim as new, and desire to secure by 1. A polisher'comprising in combination, a' portable motor, a pair of handles secured thereto and fprojecting laterally. therefrom, said handles-"being disposed out of align-' ment with each}- other, and one of which is angularl Y adjustablewith respect to the longitudina axi f theu'notor, means for securing said adjustable handle in various positions 0'f;adjustmei1t,a spindle in alignment with and secured to the motor shaft of said motor andextendi'n'gaway from said motor and a relatively soft polishing member se.. cured to said spindle;-

2. A polisher comprising in combination, a portable motor, a pair of handles secured thereto and projecting laterally therefrom, said handles being disposed out of alignment with each other and. one o fwhich isremovable and the other of which is anguover the back of said pad, and means for securing said corners over said pad with the main portion of the sheep skm at the front of said pad to provide a polishing surface. 7
